My fx-9750GA PLUS wont graph lines, cicles or paraballas

This is not a graphing calculator. Besides, most graphing calculators are able to graph functions, and conics are not functions. You need a utility that graphs conics. The Casio FX-9750G and others have a conics utility. On the TI83/84 Plus you can download an application that draws them.

It has a reset button on the back, midway from the top.

You can not do that like you think you could. You have to enter your y= equation in to the graph and then look at the graph line to see what X equals at a certain Y. Or you can rearrange the equation. For example: y=4x+5, rearrange it to be (y-5)/4 then plug your Y-value in and it will give you the X-value.

there should be an e to the x power button and to graph would be in y= button y=(e^-2x)+3x (^ stands for exponent spot) after putting this in to the y= hit graph

If you want to manipulate 6x6 matrices, you can use one of the CASIO Graphing calculators, such as theCFX-9850GPlus, or the FX-9750G plus.
Graphing calculators from other manufacturers can also handle such matrices. The FX-115ES can handle matrices with dimensions up to 3x3.

To get results in radians you must configure the angle unit to be degree.

1. In Run screen press [SHIFT][MENU] to access (SETUP).
2. Use Down arrow to highlight the line Angle :
3. Press F2 key to select the TAB Radian.
4. Once you do that all values (input of trigonometric functions and polar graph functions OR output of inverse trigonometric functions) are in radians.

If your function is periodic (and all trigonometric functions are) set the window dimensions Xmin = negative (2 or 3)P and Xmax) = (2 or 3) PI. Adjust if necessary to a smaller domain.

Hello,
Turn calculator ON. If you do not see several icons press [MENu].
Use arrow to select the [GRAPH] application and press [EXE].
In the entry screen, the line with Y1= is highlighted. If it is not, use arrow to highlight it.
Press the right arrow, the highlighting disappears leaving you with Y1= and the blinking cursor.
At the position of the cursor enter 5 [X, theta,T] key under the [ALPHA]. On the screen appears 5X, complete you equation +2.
Press [EXE] to store function.
If you want to draw other functions, it is time to do so on that screen.
When done press [F6:Draw}.
If the screen does not show a lot of the function, you can use the arrow keys to pan the graph.
You can also press [SHIFT][V-Window] to set the window limits.

Hope it helps.

i tried to graph a simple function but it wont show the lines it will only show the graph

Hello,

Turn calculator on. Select [RUN] [EXE].
In run screen press [OPTN] [F6:-->] [F4:NUM] then select the function you want to use. You have ABS, Int, Frac, Rnd, Intg.

Hope it helps.
